The building supplies heating through five Ray Pac boilers, each rated at 175 HP, They supply the heating for the radiation from a single pipe system to the supply and return headers. In the lower portion of the building, shell and tube exchangers provide Glycol heating for those areas vulnerable to freezing. We have placed new isolation valves on the boiler systems and rebuilt the Armstrong pumps providing circulation for the boilers.

The radiation system uses Armstrong in-line pumps to provide circulation to the low profile cabinets at each office window.
Domestic hot water is heated by two ray-therm boilers located in the boiler room. It is a continuous re-circulation system and is soon to be replaced with something more efficient.
Fresh air is provided from centralized fans located on the 34th floor and the forth and fifth floor. Delivery of the air into the tenant areas is from a variable air volume system. The volume these fans bring to the building is large. There is no need to start the chillers until late into the season. There are a total of seventeen main air fans providing fresh air to the building. The chillers are 900 ton, Trane units they are in series with each other. They are typically started when the outdoor temperature is above 12 deg. C.
The operations manager is Ken Edmunds, the chief engineer is Jason Bartlett, the maintenance tech is Bill Thompson and Mike Tolentino looks after T.R.'s. This is a very fine crew, to look at the work they have accomplished in the last two years is short of amazing. They worked closely with the consulting engineers and base building contractors to perform most of the work in the bio. Good work guys and the best in the future. We hope you will honor us with a tour,when you are done.
Oxford bought the Shell Centre building in the fall of 1998. There was a demand to improve the property. We prioritized the needs of the building and implemented those changes. The work continues but the last two years have seen many changes. With the help of the mechanical consultants and electrical consultants to verify the requirements for change, you will find below some of the work that is or, soon will be completed.

• Oxford built out a central control, monitoring room on the main floor, and brought all the system controls to this room where it is monitored 24/7.
• We added sprinkler coverage to include all electrical rooms (4) on each floor and included a pre-action system for each of the two main electrical vaults.
• Installed in each ped-way was a pre-action system to protect it in the event of cold weather.
• The excess pressure pump was replaced and relocated in the parkade main sprinkler room.
• Extra transformers were added to the floors to increase capacity available for the tenants use.
• Replaced the transformer switches, which were becoming out dated with a more sophisticated model.
• Added glycol ramp heating to the parkade entrance.
• Increased the amount of CO sensors to the parkade.
• Preparing to install a new security system.
• Added better control to the elevators using more efficient drive motors.
• Added water softeners for the sprays for humidity control.
• Installed a guard rail around the cooling tower well.
• Replaced the central soap system with local dispensers at each washbasin.
• Up graded the HVAC control from the JC 85/40 to Metasys at the panel level removing the gateways.
• We are half way through replacing the entire chilled water coils in the fans of the building.
• Replaced the rolled pre-filters of the fans with framed, replaceable pads.
• Replaced the reciprocating pneumatic pumps with sliding vane style for the control air to the building.
• Replaced a shell and tube heat exchanger for the lower heating with a plate exchanger and added larger pumps for increased capacity and flow.
• Added mechanical cooling to the transformer vaults and replaced the units serving the elevator machine rooms.
• Added to the building a dry type (air) closed condenser loop (glycol) and ran the loop through the tower for the tenants to use. We as well use it for the condensing for the A/C units for the elevator machine rooms and the transformer vaults.
• We as well installed radiation control valves and isolation valves for the perimeter heating system. Previous there was no control the heating had no control except the temperature. This was our largest under taking as it affected almost every tenant of every floor. Pneumatic control was given to those thermostats of the perimeter, between each riser.
